The bottom walls 140 of the four frame profiles 100 each comprise an inner cavity profile 600, the inner cavity profile 600 being located directly below the assembly cavity 300.

Four frame section bars 100 are two long limit section bars that distribute side by side and two minor face section bars that distribute side by side respectively, and the length direction of long limit section bar is unanimous with the length direction of minor face section bar to the length of long limit section bar is greater than the length of minor face section bar, and the logical groove 200 of assembly on the long limit section bar is used for the longer side sealing connection with photovoltaic module 400, and the logical groove 200 of assembly on the minor face section bar is used for the shorter side sealing connection with photovoltaic module 400.

In order to facilitate the installation operation of the assembly frame device, the bottom walls 140 of the two long-side profiles further comprise outer installation parts 700, the outer installation parts 700 and the inner cavity forming part 600 are located on the same plane, and the outer installation parts 700 are located on one sides of the assembly cavities 300, which are back to the notches of the assembly through grooves 200; two through holes 702 distributed at intervals along the length direction of the outer installation part 700 are arranged on the outer installation part 700, a bolt 800 penetrates through the inner side of each through hole 702, a pressing block 900 is in threaded fit with the bolt 800, the head of the bolt 800 is located above the outer installation part 700, the pressing block 900 is located below the outer installation part 700, and the width of the outer installation part 700 is smaller than the depth of the groove of the assembly through groove 200.
